ABSTRACT:
An inflatable seal comprises a flexible active part and a rigid part which together define a chamber to be pressurized to place the active part in its operative position and to be evacuated to place the active part in its inoperative position, the active part being made from a composite material comprising an elastic material in which a wide deformable mesh of fibers of low extensibility is incorporated such that the active part has anisotropic elasticity and mechanical strength sufficient to withstand the differential pressures extend thereon in its operative and inoperative positions without the need for external reinforcements.
